The correct order of increasing electrical conductance is

Question

The correct order of increasing electrical conductance is (A) BeH2 < CaH2 < TiH2 (B) BeH2 < TiH2 < CaH2 (C) CaH2 < BeH2 < TiH2 (D) TiH2 < CaH2 < BeH2

Tardigrade Admin · Accepted Answer

BeH2 is a covalent hydride. Therefore, it does not conduct electricity. CaH2 is an ionic hydride. Therefore, it conducts electricity in molten state. TiH2 is metallic hydride. Therefore, it is a good conductor of electricity. ∴ Order of electrical conductance is BeH2 < CaH2 < TiH2

Q. The correct order of increasing electrical conductance is

$B e H_{2} < C a H_{2} < T i H_{2}$

$B e H_{2} < T i H_{2} < C a H_{2}$

$C a H_{2} < B e H_{2} < T i H_{2}$

$T i H_{2} < C a H_{2} < B e H_{2}$

Q. The correct order of increasing electrical conductance is

BeH2​<CaH2​<TiH2​

BeH2​<TiH2​<CaH2​

CaH2​<BeH2​<TiH2​

TiH2​<CaH2​<BeH2​

BeH2​ is a covalent hydride. Therefore, it does not conduct electricity. CaH2​ is an ionic hydride. Therefore, it conducts electricity in molten state. TiH2​ is metallic hydride. Therefore, it is a good conductor of electricity. ∴ Order of electrical conductance is BeH2​<CaH2​<TiH2​

$B e H_{2} < C a H_{2} < T i H_{2}$

$B e H_{2} < T i H_{2} < C a H_{2}$

$C a H_{2} < B e H_{2} < T i H_{2}$

$T i H_{2} < C a H_{2} < B e H_{2}$
